Details please: why monstrous 16MB post_max_size needed for zabbix-frontend?

[xabbiz]

zabbix-frontend requirements need post_max_size of 16M - seriously, what is zabbix posting so big that it needs this setting? Could please anybody explain why is a monitoring frontend posting such an enormous amount of data to the webserver? What is it? I mean is there a feature where people can upload videos or why is that needed? Seriously interested in these details, thanks!

In this buffer usually are stored data about things which you are changing.
More hosts and items is changed in single update/add/delete change than this buffer needs to be bigger.
Solution/workaround: do all necessary changes in smaller batches.
Problem is only that on changing for example template which is already used on growing number of hosts minimum size of this buffer needs to be bigger and bigger.

I think importing templates and other things is the first place people hit the limits.

Yep thse operations as well.

16M of string data is a lot, you can put lots of templates there - I smell some web gui anti-pattern here. No application should ever need to send such a big amount of post data, except image and video cms of course.
Will investigate if time permits.
